Making your own Beef Lombardi Casserole is easier than you might think. Just follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Cook the Beef: In a large skillet over medium heat, brown the ground beef until cooked through. Drain off excess fat.
3. Add Aromatics: Add the chopped onion and minced garlic to the skillet, cooking until the onion becomes translucent (about 3-5 minutes).
4. Incorporate Tomatoes: Stir in the tomato sauce, diced tomatoes, water, Italian seasoning, salt, and pepper. Let it simmer for about 10 minutes.
5. Prepare Noodles: Meanwhile, cook the egg noodles according to package instructions until al dente. Drain and set aside.
6. Mix Cheeses: In a separate bowl, combine the sour cream, cottage cheese, and 1 cup of mozzarella cheese. Mix until well blended.
7. Combine Ingredients: In a large mixing bowl, combine the beef mixture, cooked noodles, and cheese mixture. Mix until well combined.
8. Transfer to Baking Dish: Pour the combined ingredients into a greased 9×13 inch baking dish. Spread evenly.
9. Top with Cheese: Sprinkle the remaining mozzarella cheese and Parmesan cheese on top.
10. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is bubbly and light golden brown.
11. Cool and Serve: Allow the casserole to cool for a few minutes before serving. Garnish with fresh parsley if desired.
